When comparing EJS vs Vue.js, the Slant community recommends Vue.js for most people. In the question“What are the best JavaScript templating engines?”Vue.js is ranked 3rd while EJS is ranked 5th. The most important reason people chose Vue.js is:

Vue can easily be integrated with other front-end libraries. This makes it an extremely versatile tool and it's easy to fix its shortcomings or missing features by just plugging in another library.

Pros

Pro

Complete JavaScript logic

EJS uses all the JS jargon and logic, so if you're proficient in JS, you can use EJS right away.

Pro

Consistently scores rather well in benchmarks

According to some benchmark tests, EJS is way faster than Jade or Haml.

Pro

Same language before and after rendering

Your html/text remains pretty much the same before and after rendering. EJS filters out and performs its functions on any occurrences of its own <%= %> tags in your template.

Pro

Powerful error handling

EJS has a really smart error handling mechanism built right into it. It points out to you, the line numbers on which an error has occurred, so that you don't end up looking through the whole template file wasting your time in searching for bugs.

Pro

Can be used with any front-end stack

Vue can easily be integrated with other front-end libraries. This makes it an extremely versatile tool and it's easy to fix its shortcomings or missing features by just plugging in another library.

Pro

Lightweight

Vue.js weighs in at 16kb min+gzip.

Pro

Single file component

Very useful.

Pro

Responsive server-side rendering

Since most of the mainstream server-side rendering implementations are synchronous, they can block the server's event loop when the application is complex.

Vue implements streaming server-side rendering, which allows you to render your component, get a readable stream and directly pipe that to the HTTP response. This allows you to have a responsive server and decreases the time your users have to wait before they get your rendered content.

Pro

SEO friendly

Starting with Vue 2.0, Vue supports server-side rendering. This helps with SEO a lot, since the views are rendered directly on the server, which are indexed by search engines.

Pro

Vuex store, events system

Pro

Support for both templates and JSX

You can choose to use either a templating language, or if you feel it's necessary to drop on a lower virtual-dom level, you can use JSX. This is simply done by replacing the template option with a render function.

Or alternatively, you can embed functions inside templates by using the <render> tag.

Pro

Supports inline templating

Although you can build components in JavaScript files, you can also use inline handlebars-like templating in your HTML views where simplicity is often a more sane choice.

Pro

Can be made even lighter

Since the template-to-virtual-DOM and compiler can be separated, you can compile the templates in your machine and then deploying only the interpreter which is 12KB minified and gzipped.

Pro

CLI and Webpack integration

Pro

Reactivity system

Pro

VueRouter

Cons

Con

No support for block by default

EJS has no support for the block functionality which allows you to reuse pieces of templates across different files. Although it can be added to EJS through a third-party library.

Con

Cryptic syntax

Much more difficult to read, especially for designer/HTML people who don't write JavaScript.
